Please see the README for instructions common to all platforms and
descriptions of the options mentioned here.


	Linux.

Most modern Linux distributions use Linux-PAM with a password changing
module which understands "use_authtok".  Thus, you may choose which
module prompts for the old password, things should work either way.


	FreeBSD.

Currently, FreeBSD doesn't use PAM for password changing.  This means
you won't be able to use pam_passwdqc with FreeBSD.


	Solaris.

pam_passwdqc has to ask for the old password during the update phase.
Use "ask_oldauthtok=update check_oldauthtok" with pam_passwdqc and
"use_first_pass" with pam_unix.

You will likely also need to set "max=8" in order to actually enforce
not-so-weak passwords with the obsolete "traditional" crypt(3) hashes
that most Solaris systems use.  Of course this way you only get about
one third of the functionality of pam_passwdqc.
